We have three Windows 2000 machines talking through a hub, and we are trying to upgrade so we bought a Windows 7 machine to add to the network. All of the Win2K machines can access the public directory on the Windows 7 machine, but the Windows 7 machine cannot access the other Win2K machines -- we just keep getting a pop-up asking for network user name and password.

Thank you. This has worked for one of my machines (the Win7 machine can now access one of the Win2K machines) I will try to see what the problem is with the other 2 win2K machines.

Check your Windows Policy Editor for network/security settings. As I recall there's a setting in Windows 7 to allow compatibility with older versions of Windows, but in order to get this you have to lower the security requirements.

If you're behind a firewall, then this isn't a big deal unless the general public are able to connect their laptops to the inside of your network (e.g., your company is a public library).

If you don't have a firewall, then a router such as one of the LinkSys wireless/broadband routers can provide NAT for you, and you should seriously consider getting one of these.
